- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Weldability & Machinability
6061-T6 aluminum is a heat-treatable alloy with magnesium and silicon as its primary alloying elements, offering a versatile combination of high strength, good workability, and excellent corrosion resistance. Conforming to ASTM B211, its T6 temper indicates it has been solution heat-treated and artificially aged to achieve optimal mechanical properties, making it a go-to material for general fabrication and structural applications.
As a medium-width bar, this 2-1/2" x 3/4" size is perfectly suited for structural bracing, machine ways, wear strips, and mounting plates. Its substantial cross-section provides rigidity and strength for support members, while remaining lightweight and easy to machine for custom parts.
